rIhis invention relates to improvements in the building art andparticularly to walls of that type set forth and to be erected inaccordance with the general plans set forthrin the ivalrowski Patent No.1,579,377. According to the teachings of said patent the wall is made upof supporting studs and then lathing v strips are laid proiniscuouslyacross the face of the studs and fastened to the studs and to eachother` in whatever position they may chance to be laid relative to thestuds. lathing strips are then plastered over or oth'- erwise treated asmay be Ydesired to finish the wall.

The present invention is directed particularly to a specific method andmeansfor fastening the plaster lath when laid against the studs inaccordance with the theories of said above named patent, in a rapid andeffective manner, and with the operator being corn-V i. several viewsFig. 1 is a perspective viewY of a fragrnenfV tary portion, of anumber'of coursesv ofthe wall secured to the vertical studs inaccordance'with our present invention.

Referring now more `particularly to the l" characters' of reference onthe drawings, `the numeral lV designates the .upright metal studs whichare of the usual channel shape, and the legs la of which arepreferablyprovided-y fitli v' the inside beveled surfaces as at 16.

lath which for the purpose of the applica tion of the presentinventiomis made in strips approximately VslX feet long and'l from The numeral 2designates the plaster board twelve to eighteen inches wide.V rlheordinances of most l.cities vrequire' that' the lath be secured to thestudding at' various points,

usually about six/inches; apart,Y and to that endl in carryingoutourpresent invention the lathis provided witha series of longitudinal slotscut throughthe lath at the fas tening points, and beingof a suiiicientlength to allow-thelath to. be shifted one way orthe other to: fastening.positionfin accordance i with the practices taught by theaboveiden'- ntilied patent. l/Vhen thus positioned the slots 3 will usually lie'immediately adjacent and from side to side of astudzand willthen befixed tightly againstthe stud by. means of the use of thefollowingmethod and instrui mentalities, toswit:

. vvVe provide a. fastening element: compris- Y ing a clip orlikelelement having-a flat front face and intermediate prongs 5 and pro-1 jecting atfright angles to the'face 4. The prong 6 Vhas a detent 7projecting at substantialiy right angles thereto, the Zinner face ofAsaine as at 8 bein(Y beveled to substantially conform to the bevel l?)of theleg la ofthe channel 1 when the` detent is lmoved into frictionalengagement therewith. The dis? tance between the body. andthe beveledrvsurface of the prong is slightly less Ythan ytire Ycombined widths ofthe lathand beveled leg ofthe stud so that'y the Vwedgingaction here--after described may be had.

The fastening element is preferably positioned by means of the followingoperation:

Itis first placed within the co-acting jaws of the ypinching tool 9,which 'may be of any 'desired type. rEhe tool carrying the fasteningelement is then projected throughthe slot 3. The distance between theprong 5 and the end of the detent 7 is sufficiently wide to alloW thesame to straddle the stud l, as clearly shown in F ig. 2. When thefastening element has been positioned so that the at surface 4 isagainstthe face of the lath the tool 9 is operated `to pinch the prongs 5 and6y towards each other. This causes the beveled surface 8 of the detent 7to ride the'beveled surface 1b of the leg la and brings the prong 5 intodirect frictional contact with the flat side of the stud l. surfaces 8and 1b have a Wedging effect to draw the flat plate 4 into closefrictional engagement with the front face of the lath and to force sameinto tight contactagainst the stud, and the engagement of the ydetent 7with the leg of the stud and of the prong 5 against the flat of the studholds the fastening element securely in position, as Will be apparent.

rEhus the lath may be fastenedV at a plurality of the points along thestud and the free meeting ends of the lath off the stud are fastened toeach other and to the edges of the adjacent laths by the clips l0 in themanner andform shown. in the patent mentioned in the preamble to thisspecification.

It Will be apparent vfrom this descrigtionV that by means of ourimproved method and instrumentalities plaster board'lath may be quicklymounted against the metal stud'and there securely fastened at a numberof points in a most admirable Way and With a minimum expense of time)labor and material7 all of which is quite essential to en efficient andeconomical erection of Walls of this type in class A buildings.

Having thus described our invention What We claim as new and useful anddesirejto se-y cure by Letters Patent is:

A fastening element for use in securing plaster lath to a channel studthe inner face of the leg of which is beveled, comprising a body andprojecting prongs, one prong having a detent at one end thereof, theinner surface of the detent being beveled and the distance from the bodyto the beveled surface being less than the combined Width of the lathand'stud leg which are to be joined together, the two prongs lyingnormally in the same plane and the detent prong being bent in that planeout of its stud engaging position.

In testimony whereof We affix our signatures.
